5. Remove the dipstick again and check the oil
level. It should be between the H (High) and
L (Low) marks
sB. This is the normal oper-
ating oil level range. If the oil level is below
the L (Low) mark
sA, remove the oil filler cap
and pour recommended oil through the
opening.Do not overfill
sC.
6. Recheck oil level with the dipstick.
It is normal to add some oil between oil
maintenance intervals or during the

the parking brake.
2. Start the engine and let it idle until it reaches
operating temperature, then turn it off.
3. Remove the oil filler cap by turning it coun-
terclockwise.
4. Place a large drain pan under the drain plug.
5. Remove the drain plug with a wrench by
turning it counterclockwise and completely
drain the oil.

CHECKING PARKING BRAKE
From the released position, firmly push the park-
ing brake down. If the number of clicks is out of
the range listed, see a NISSAN dealer.
c3–4 clicks under depressing force of 44 lb
(196 N) .
CHECKING BRAKE PEDAL
With the engine running, check the distanceA
between the upper surface of the pedal and the
metal floor. If it is out of the range shown, see a
NISSAN dealer.
Distance A: Under depression force of
110 lb (490 N)
3 1/2 in (90 mm) or more
Self-adjusting brakes
Your vehicle is equipped with self-adjusting
brakes.The front and rear disc-type brakes self-adjust
every time the brake pedal is applied.
WARNING
See a NISSAN dealer for a brake system
check if the brake pedal height does not
return to normal.
Brake pad wear indicators
The disc brake pads on your vehicle have audible
wear indicators. When a brake pad requires re-
placement, a high pitched scraping or screech-
ing sound will be heard when the vehicle is in
motion. The noise will be heard whether or not the
brake pedal is depressed. Have the brakes
checked as soon as possible if the wear indicator
sound is heard.
Under some driving or climate conditions, occa-
sional brake squeak, squeal or other noise may
be heard. Occasional brake noise during light to
moderate stops is normal and does not affect the
function or performance of the brake system.
Proper brake inspection intervals should
be followed.For more information regarding
brake inspections, see the appropriate mainte-
nance schedule information in the “NISSAN Ser-
vice and Maintenance Guide”.

BRAKE BOOSTER
Check the brake booster function as follows:
1. With the engine off, press and release the
brake pedal several times. When brake
pedal movement (distance of travel) remains
the same from one pedal application to the
next, continue on to the next step.
2. While depressing the brake pedal, start the
engine. The pedal height should drop a little.
3. With the brake pedal depressed, stop the
engine. Keep the pedal depressed for about
30 seconds. The pedal height should not
change.
4. Run the engine for one minute without de-
pressing the brake pedal, then turn it off.
Depress the brake pedal several times. The
pedal travel distance will decrease gradually
with each depression as the vacuum is re-
leased from the booster.
If the brakes do not operate properly, have the
brakes checked by a NISSAN dealer.
ENGINE COMPARTMENT
CAUTION
Never use a fuse of a higher or lower
amperage rating than specified on the
fuse box cover. This could damage the
electrical system or cause a fire.
If any electrical equipment does not come on,
check for an open fuse.
1. Be sure the ignition switch and the headlight
switch are OFF.
2. Open the engine hood.3. Remove the fuse box cover by pushing the
tab and lifting the cover up.
4. Remove the fuse with the fuse puller. The
fuse puller is located in the center of the fuse
block in the passenger compartment.

southern Idaho, western South Dakota, western
Nebraska, and the part of Texas which is directly
south of New Mexico.
Using unleaded gasoline with an octane
rating lower than stated above can cause
persistent, heavy “spark knock.” (“Spark
knock” is a metallic rapping noise.) If se-
vere, this can lead to engine damage. If you
detect a persistent heavy spark knock even
when using gasoline of the stated octane
rating, or if you hear steady spark knock
while holding a steady speed on level
roads, have a NISSAN dealer correct the
condition. Failure to correct the condition
is misuse of the vehicle, for which NISSAN
is not responsible.
Incorrect ignition timing may result in spark
knock, after-run and/or overheating, which may
cause excessive fuel consumption or engine
damage. If any of the above symptoms are en-
countered, have your vehicle checked at a
NISSAN dealer.
However, now and then you may notice
light spark knock for a short time while
accelerating or driving up hills. This is not a
cause for concern, because you get the
greatest fuel benefit when there is light
spark knock for a short time under heavy
engine load.
ENGINE OIL AND OIL FILTER
RECOMMENDATION
Selecting the correct oil
It is essential to choose engine oil with the cor-
rect quality and viscosity to ensure satisfactory
engine life and performance. NISSAN recom-
mends the use of a low friction oil (energy con-
serving oil) in order to improve fuel economy and
conserve energy. Oils which do not have the
specified quality label should not be used as they
could cause engine damage.
Only those engine oils with the American Petro-
leum Institute (API) CERTIFICATION MARK onthe front of the container should be used. This
type of oil supersedes the existing API SG, SH, or
SJ and Energy Conserving II categories.
If you cannot find engine oil with the API CERTI-
FICATION MARK, use API grade SL Energy
Conserving oil. An oil with a single designation
SL, or in combination with other categories (for
example, SL/CF) may also be used if one with the
API CERTIFICATION MARK cannot be found. An
ILSAC grade GF-III oil can also be used.
NISSAN recommends mineral based oils. These
oils must, however, meet the API quality and SAE
viscosity ratings specified for your vehicle.

cCheck your hitch, trailer wiring harness con-
nections, and trailer wheel lug nuts after 50
miles (80 km) of travel and at every break.
cWhen stopped in traffic for long periods of
time in hot weather, put the vehicle in the P
(Park) position.
When towing a trailer, final drive gear oil
should be replaced and transmission
oil/fluid should be changed more fre-
quently. For additional information, see the
“Maintenance and do-it-yourself” section
earlier in this manual.
Tow mode
Tow mode should be used when pulling a heavy
trailer or hauling a heavy load. Press the tow
button to activate the tow mode. The tow indica-
tor in the instrument panel illuminates when the
tow mode is selected. Press the Tow button
again to turn the tow mode OFF. The Tow mode is
automatically cancelled when the key is turned
OFF.
The Tow mode does the following:
cReduces transmissions shifts when pulling a
trailer or hauling a load.
cProvides similar shift feel to driver when the
vehicle is towing.The Tow mode should be used when the vehicle
and trailer weight is at least 75% of the vehicle’s
GCWR. Tow mode is most useful in the following
driving conditions when towing a heavy trailer or
hauling a heavy load:
cRolling terrain.
cStop and go traffic.
cBusy parking lots.
Driving the vehicle in the Tow mode with no
trailer/load or light trailer/light load will not cause
any damage. However, fuel economy may be
reduced and the transmission/engine driving
characteristics may feel unusual.
When towing a trailer, final drive gear oil
should be replaced and transmission
oil/fluid should be changed more fre-
quently. For additional information, see the
“Maintenance and do-it-yourself” section
earlier in this manual.
FLAT TOWING
Towing your vehicle with all four wheels on the
ground is sometimes called flat towing. This
method is sometimes used when towing a vehicle
behind a recreational vehicle, such as a motor
home.
CAUTION
cFailure to follow these guidelines can
result in severe transmission damage.
cWhenever flat towing your vehicle, al-
ways tow forward, never backward.
cDO NOT tow any automatic transmis-
sion vehicle with all four wheels on the
ground (flat towing) . Doing so WILL
DAMAGE internal transmission parts
due to lack of transmission lubrication.
cFor emergency towing procedures refer
to “Towing recommended by NISSAN”
in the “In case of emergency” section of
this manual.
Automatic Transmission
To tow a vehicle equipped with an automatic
transmission, an appropriate vehicle dollyMUST
be placed under the towed vehicle’s drive
wheels.Alwaysfollow the dolly manufacturer’s
recommendations when using their product.
